: We purchased a McPherson upflush toilet about 3 years ago and now it seems to want to overflow all the time. We think it has a bad valve, but since the company is no longer in business we can't get parts. If anyone is interested we will sell this unit. All of it is in great shape and was not used much since it was in the basement.

PLEASE CONTACT ME AT MY E-MAIL AS I WOULD LIKE TOHAVE YOU TO EXPLAIN THE EXACT PROBLEM. I HAVE BEEN WORKING ON THE FUNTIONS OF THISMCPHERSON TOILET NOW FOR A PERIOD OF TIME .
